[Xen-devel] xentrace buffering

[pak333@xxxxxxxxxxx]

Hi,

I am looking at the xentrace code and it looks like the individual cores/cpus write their (trace data) into individual regions of memory and they are all collected by xentrace and processed.

I would like to have one trace buffer for all cores so that I can get an exact sequence in time order of the events that have occurred over the sampling period across cores/cpus.

Is that easily doable>? If so, any pointers can someone send me pointers as to where I should start looking at modifying. 

Thanks
